How do you prevent acrylic from cracking when drilling holes?

To prevent acrylic from cracking when drilling holes, it's important to use a sharp drill bit designed for plastics, such as a brad point or specialty acrylic bit. Additionally, drill at a slow speed to reduce heat buildup, and apply light pressure to avoid stressing the material. Clamping the acrylic securely and using a backing board can also help prevent chipping and cracking during the drilling process. Finally, consider pre-drilling a smaller pilot hole before enlarging to the desired size.
